A 32-year-old La Center, Wash. mother and her 10-year-old son are in critical condition at OHSU Hospital after a collision Friday afternoon with a wrong-way driver on Interstate 5 near Vancouver.

The collision killed Ericka Gorremans' 6-year-old nephew.

Police said that 84-year-old Gage Musgrave of Vancouver was headed south in the northbound lanes of Interstate 5 near milepost 10 when he crashed into the car driven by Gorremans. Gorremans' car then struck a pickup truck driven by Darren R. Watts, 46, of Vancouver. Watts' car then struck Musgrave's car, according to a press release from Washington State Patrol Trooper William Finn.

Musgrave is in satisfactory condition at PeaceHealth Southwest Medical Center, according to a nursing supervisor. Watts was uninjured.

Finn said the investigation is continuing. Alcohol and drugs do not appear to be a factor, he said. The children's names are not being released until police decide whether they will file criminal charges in the case, he said.
